java - 命名 Hibernate 查询的 "Named query not known"？

Question

可能是什么问题？

@Entity
@NamedQueries( {
    @NamedQuery(name = User.ALL,
                query = "SELECT u FROM User u")
})

public class User {
    public static final String ALL = "User.all";
}

public class Service {
    find... with ... User.ALL
}

堆栈跟踪:

不确定这是否是您的问题，但请查看这篇文章 here .

问题在于使用:

org.hibernate.annotations.Entity

代替:

javax.persistence.Entity
